Detox A year in. Building it, Testing with it
summary
Detox claims deterministic end-to-end tests by embedding a gray-box synchronization agent that waits for app idle and invokes native methods via a JSON reflection protocol, extending EarlGrey/Espresso drivers. Teams move from flaky production E2E to controlled mock server build flavors (React Native 0.55 or react-native-repackager) for predictable inputs. After a year of use, CI reliability improves, parallel runners and artifact capture are upcoming, and a profiling app called Detox Instruments measures regressions.
